[Abstract]:It is an essential step for the motor to obtain the operating parameters of the equipment to analyze the performance index through a large number of tests from the development, production, operation and maintenance of the motor. In order to promote the development of motor testing technology, this paper presents a monitoring system of main control machine based on LabVIEW platform, which is based on the theory of field bus control (FCS), combined with the algorithm of motor vector control (FOC), and using DSP as the core of distributed node control. The distributed performance test of permanent magnet synchronous motor is realized. This system makes use of the opening and interchangeability of CAN bus, interconnects the test motor and the main control system in the field, and constitutes the field bus control system. The organic unification of open communication network and full distributed control system is the link between field test and control equipment. The field test motor is connected on the bus as the network node of FCS. The main control platform collects and sends the measurement and control information to the field equipment through the network, so as to realize the integration of tube, measurement and control. Based on the analysis of the current situation of the motor testing system at home and abroad and the commonly used testing methods, a permanent magnet synchronous motor performance test system based on CAN bus is designed. The distributed node uses DSP technology and FOC control algorithm to realize the operation parameter acquisition, control and CAN communication of the motor. The test results verify the high speed and high precision of the DSP controller and the feasibility of the algorithm. The master control node uses virtual instrument technology to realize the overall construction of the test system. The test results verify the openness and expansibility of the system. In this paper, the permanent magnet synchronous motor (PMSM) is taken as the test object, and the software and hardware of the test system are tested. The experimental results show that the system is stable and reliable and can be used to test the dynamic performance of distributed test motor by CAN bus. It has certain practical value in motor control performance evaluation and qualified overhaul.
